Ibaraki Hitachinaka City
A hidden retreat for adults only
"Hitachinaka Onsen Kirari Bettei" is a day-use hot spring facility for elementary school students and older. We offer a relaxing healing space where you can spend a leisurely time, with open-air baths overlooking scenic views, rock baths, saunas, and a dining area where you can enjoy house-made soba noodles.

A spacious natural hot spring with sweeping views of the seasonal rural landscape and the cityscape of Mito in the distance. You can luxuriate in the source water, which is sodium bicarbonate and chloride spring, flowing freely from the source, and its soft texture gently envelops the skin.

A full-fledged sauna where the power of far-infrared heat penetrates deeply into the body. Auto löyly, which operates periodically, spreads pleasant steam throughout the room and encourages refreshing perspiration.

A cold plunge bath that gently cools down your body after the sauna. By slowly cooling your hands and feet first, circulation throughout the body is encouraged, leaving you wrapped in a pleasant sense of refreshment.

A spacious bedrock lounge where you can enjoy pulgama, which slowly warms you with heat from a fire furnace, and several kinds of mineral stones such as black germanium and barley stone. You can enjoy detoxing together in indoor wear, moving through a variety of areas including private spaces like a beehive and comfortable ondol-style floor heating. Your overheated body is tightened up in the cool room, and you can spend an exquisite, relaxing time in the rest area.

Most of what we surveyed never even made it onto this site. This book is a further cut from what did. Our editor bathed in every onsen and sauna in it, and wrote only what they confirmed on the ground.
